Pearl nuclei from Greatwall Pearl Nucleus are precision spherical beads machined from freshwater mussel shell, composed of natural calcium carbonate. The supplier offers sizes from 2 mm to 15 mm diameter, with each bead graded by roundness, surface uniformity, and shell material consistency to ensure reliable nacre deposition during pearl cultivation.
The material is sourced from freshwater mussel shells, a standard industry practice for nucleus production due to its compatibility with oyster biology. Typical industry specifications for such nuclei include a density of approximately 2.7 g/cm³ and a Mohs hardness of 3 to 4, which are standard for calcium carbonate-based materials. Nuclei are often polished to a smooth finish to minimize tissue irritation in the host mollusk.
These nuclei are a critical consumable for commercial pearl farms producing Akoya, Tahitian, and South Sea pearls. Buyers include aquaculture enterprises and export-oriented pearl producers who require consistent bead dimensions to achieve uniform pearl sizes. Trade terms such as FOB and CIF are commonly used, with packaging designed for secure transport to prevent damage during shipping.

Before ordering, verify the exact diameter range and grading criteria for the nuclei batch you intend to purchase. Confirm that the supplier can provide a certificate of material composition and a grading report, as these documents are essential for ensuring consistency in pearl production.
Logistics details such as lead time, Incoterms, and payment terms should be clarified directly with Greatwall Pearl Nucleus. FOB and CIF are common, but buyers should confirm whether the supplier can accommodate specific shipping requirements, such as temperature-controlled transport if needed.
Quality checks should include visual inspection for roundness and surface uniformity, as well as a density test to confirm the material’s properties. Request documentation such as a material safety data sheet (MSDS) and a third-party test report for calcium carbonate content to ensure the nuclei meet industry standards.
